How about KV260 or KR260? (250K LEs, Ultrascale+ 16 nm) https://www.digikey.com/en/products/detail/amd/SK-KV260-G/13985269?s=N4IgjCBcpg7ALAJiqAxlAZgQwDYGcBTAGhAHsoBtEWAZgAYwaaQBdEgBwBcoQBlTgE4BLAHYBzEAF9JJZJCoBrAG6IAbHVaSgA https://www.digikey.com/en/products/detail/amd/SK-KV260-G/13... The price is very good for Ultrascale+. I think something could made cheaper using an Efinix Titanium chip, someone should do it. Their own dev. board is too expensive: https://www.efinixinc.com/products-devkits-titaniumti180m484.html https://www.efinixinc.com/products-devkits-titaniumti180m484...
